nuclear engines, even just the fission, are the future for the space. The thing is you'd never be able to launch them on Earth. So, the first thing is to get enough stuff into space and establish an assembly/test platform there, Moon probably. With Starship the Moon becomes just a 3 day trip for 100ton cargo while burning less than $10M of fuel. >Using these resources to improve chemical flamethrowers is sub-optimal. A dead end. Earth launch future is large rail gun (somewhere like Bolivia) as a first stage booster. Requires a bit of political will, international cooperation and a few billions. Unfortunately the 1st and 2nd aren't coming soon, so the "chemical flamethrowers" for now.
